In Kansas, it’s now up to the conscience of the pharmacist as to whether to fill a prescription.

Called the Heath Care Rights of Conscience Act, the new law will bar anyone from being required to prescribe or administer a drug they “reasonably believe” might result in the termination of a pregnancy. The law was signed Monday.

Critics say the law will open the door for a pharmacist to refuse a request for something like the “morning-after” pill, which the Mayo Clinic says can prevent or delay ovulation, block fertilization or keep a fertilized egg from implanting in the uterus.

They argued that the law puts pharmacists and physicians in a position to refuse birth control and that it will affect many women, especially those in small towns and rural communities since the health provider wouldn’t be required to provide a referral somewhere else.
